Prompt
|
|
======
|
|
|
|
Loads prompt [themes][1].
|
|
|
|
Settings
|
|
--------
|
|
|
|
### Prompt Theme
|
|
|
|
To select a prompt theme, add the following to *zpreztorc*, and replace **name**
|
|
with the name of the theme you wish to load. Setting it to **random** will load
|
|
a random theme.
|
|
|
|
```sh
|
|
zstyle ':prezto:module:prompt' theme 'name'
|
|
```
|
|
|
|
### Prompt Display Length
|
|
|
|
To change working directory prompt display length from 'short', set the
|
|
following to 'long' (without `~` expansion) or 'full' (with `~` expansion)
|
|
in *zpreztorc*.
|
|
|
|
```sh
|
|
zstyle ':prezto:module:prompt' pwd-length 'short'
|
|
```
|
|
|
|
### Display Return Value
|
|
|
|
Some prompts display the return value in the prompt. If a prompt has support,
|
|
this can be disabled with the following snippet.
|
|
|
|
```sh
|
|
zstyle ':prezto:module:prompt' show-return-val 'no'
|
|
```
|
|
|
|
Theming
|
|
-------
|
|
|
|
A prompt theme is an autoloadable function file with a special name,
|
|
`prompt_name_setup`, placed anywhere in `$fpath`, but for the purpose of this
|
|
project, themes **should** be placed in the *modules/prompt/functions*
|
|
directory.
|
|
|
|
### Theme Functions
|
|
|
|
There are three theme functions, a setup function, a help function, and
|
|
a preview function. The setup function **must** always be defined. The help
|
|
function and the preview functions are optional.
|
|
|
|
#### `prompt_name_setup`
|
|
|
|
This function is called by the `prompt` function to install the theme. This
|
|
function may define other functions as necessary to maintain the prompt,
|
|
including a function that displays help or a function used to preview it.
|
|
|
|
**Do not call this function directly.**
|
|
|
|
The most basic example of this function can be seen below.
|
|
|
|
```sh
|
|
function prompt_name_setup {
|
|
PROMPT='%m%# '
|
|
RPROMPT=''
|
|
}
|
|
```
|
|
|
|
#### `prompt_name_help`
|
|
|
|
If the `prompt_name_setup` function is customizable via parameters, a help
|
|
function **should** be defined. The user will access it via `prompt -h name`.
|
|
|
|
The most basic example of this function can be seen below.
|
|
|
|
```sh
|
|
function prompt_name_help {
|
|
cat <<EOH
|
|
This prompt is color-scheme-able. You can invoke it thus:
|
|
|
|
prompt theme [<color1>] [<color2>]
|
|
|
|
where the color is for the left-hand prompt.
|
|
EOH
|
|
}
|
|
```
|
|
|
|
#### `prompt_name_preview`
|
|
|
|
If the `prompt_name_setup` function is customizable via parameters, a preview
|
|
function **should** be defined. The user will access it via `prompt -p name`.
|
|
|
|
The most basic example of this function can be seen below.
|
|
|
|
```sh
|
|
function prompt_name_preview {
|
|
if (( $# > 0 )); then
|
|
prompt_preview_theme theme "$@"
|
|
else
|
|
prompt_preview_theme theme red green blue
|
|
print
|
|
prompt_preview_theme theme yellow magenta black
|
|
fi
|
|
}
|
|
```
|
|
|
|
### Hook Functions
|
|
|
|
There are many Zsh [hook][2] functions, but mostly the *precmd* hook will be
|
|
used.
|
|
|
|
#### `prompt_name_precmd`
|
|
|
|
This hook is called before the prompt is displayed and is useful for getting
|
|
information to display in a prompt.
|
|
|
|
When calling functions to get information to display in a prompt, do not assume
|
|
that all the dependencies have been loaded. Always check for the availability of
|
|
a function before you calling it.
|
|
|
|
**Do not register hook functions. They will be registered by the `prompt` function.**
|
|
|
|
The most basic example of this function can be seen below.
|
|
|
|
```sh
|
|
function prompt_name_precmd {
|
|
if (( $+functions[git-info] )); then
|
|
git-info
|
|
fi
|
|
}
|
|
```
|
|
|
|
Troubleshooting
|
|
---------------
|
|
|
|
### Fonts aren't displaying properly.
|
|
|
|
On most systems, themes which use special characters need to have a patched font
|
|
installed and configured properly.
|
|
|
|
Powerline provides some information on [terminal support][4] and [how to install
|
|
patched fonts][5] which should fix most font issues.
